Eric the Heater GuyThis isn't legal advice — your city and fire marshal have the final word. But after years of commercial installs, here's what almost always matters:
- Clearances from combustibles
Every model publishes minimum distances to walls, ceilings, and overhangs. We spec to those numbers — not to vibes.
- Placement & egress
Heaters can't block exits or sit where guests brush against them. Layout is part of the plan, not an afterthought.
- Ventilation for gas units
Combustion needs air. Enclosed or low-clearance spaces change which models are appropriate.
- Fuel storage & lines
Propane storage rules and gas line work have their own requirements — gas work goes through a licensed installer on request.
- Enclosed-flame options
In strict jurisdictions, enclosed-burner models (like SunStar's, rated to 40-mph wind with no open flame) take the fire question off the table.
